HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 233,328, dated October 19, 1880. Application filed June 12, 1880. (No model.)

To all whom it may concern:

Be it known that I, THOMAS GoNNri'LLY, a citizen of the United States, residing in the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Heating Apparatus, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 is a top or plan view of the apparatus embodying my invention. Fig. 2 is a vertical section thereof.

Similar letters of reference indicate corresponding parts in the two figures.

My invention consists of a portable heater or fire-pot, serviceable for plumbers and others, for heating solder, soldering-irons, and other articles, and for other purposes. I employ a stand, a peculiarly-constructed burner supplied with oil or inflammable fluid under pressure, a reservoir having a common inlet for the fluid and the blast or pressure, and a bundle of wires or equivalent in the pipe between the reservoir and burner, the wires projecting beyond the pipe and covered by a removable cap, so that the wires may be withdrawn for cleansing, &c., and reinstated as required, as will be hereinafter set forth.

Referring to the drawings, A represents the reservoir for the oil or fluid, which is admitted thereinto through the cock A, the lower end of which is threaded so that the cock may be readily removed and applied.

B represents avertical pipe, which leads into the reservoir to near the bottom thereof, and is connected to a horizontal pipe, B, whose inner end communicates with the descending passage b of the burner O, which consists of a tubular piece properly supported on the reservoir A, in the present case by the pipes B B, and having its mouth at top, a stand, D, being properly sustained on the reservoir A and overhanging the burner.

It will be noticed that the horizontal branch or pipe B passes across the top of the burner,

the adjacent portion being a swell, a, the base whereof is perforated, as at a, so that enlarged space'exists between the burner and the portion of the pipe B within the same, to permit ascent of the large volume of vapor generated, and a large perforated surface is provided for the admission of air to the vapor. The perforated bottom b of the burner forms an auxiliary burner for primarily burning the oil prior to vaporization thereof.

The bottom proper of the auxiliary burner, which is a tubular extension of the tube 0, is closed to prevent dropping of the oil both as it leaves the orifice e and burns, the perforations of the side admitting air to the burning oil to produce the proper combustion thereof prior to vaporization, the head of the valve E being at the side of the burner and practically away from the heat of the auxiliary or primary burner b,

The descending passage bis continued laterally into the burner C as a branch, (1, which has an orifice or outlet, e, communicating with the interior of the burner, and a valve, E, for covering and uncovering said outlet.

Within the pipe B are a number of wires or strands, F, bundled or united, and accessible, removable, and appliable by means of a cap, F, at the end of the pipe B.

The cock A is removed so that the inflammable oil or fluid may be introduced through the uncovered opening into the reservoir. Then the cock is restored and the reservoir charged with compressed air, which may be accomplished by simply blowing air from the lungs through said cock A, the upper end whereof is a mouth-piece, f. The cock is then closed and the oil or fluid under pressure rises in the pipe B, enters pipe B and passage b d, and escapes to the bottom of the burner, where it is ignited, the resultant heat subsequently vaporizing the oil as it is fed forward, it being noticed that the shell of the burner, the branch d, passage b, and end of the pipe B which passes through the burner are exposed to the heat. The burning vapor, uniting with the oxygen of the atmosphere admitted through suitable vents in the burner, produces a flame of great heat, which is adapted to act on the articles to be heated, 850., supported on the stand D.

The wires or strands F serve to separate the particles of oil or fluid and prevent the flow thereof in a solid stream, whereby the vaporizing is most readily accomplished. Furthermore, said wires or strands serve to collect the impurities of the oil or fluid, which may be emery p removed by displacing the wires or strands B, combined and operating substantially as to and properly cleansing them.

Having thus described my invention, what I claim as new, and desire to secure by Letters 5 Patent, is-

1. The burner consisting of a tubular piece having a vertical passage, b, bottom horizontal passage. d, bottom auxiliary burner, b, perforated swell a a, and top horizontal pipe,

and for the purpose set forth.

2. The pipe B, with wires extending beyond the pipe, in combination with the removable cap F, whereby said wires may be withdrawn and reinstated, substantially as set forth.
